I would like that too, but there's no easy fix that doesn't have
downsides as far as I am aware. We could make the temp install a build
target that the tests depend on, but for historical reasons in meson
that means that the 'all' target depends on temp-install. Which isn't
great.
My current thinking is that we should get away from needing the
temporary install and instead allow to run the tests against the build
directory itself. The temp-install adds a fair bit of overhead and
failure potential. The only reason we need it is that a) initdb and a
few other programs insist that postgres needs to be in the same
directory b) contrib modules currently need to reside in one single
directory.
